' BAIL-TIE.

To all whom it may concern:

Be it known that I, CHARLES H. MCBRIDE, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Rail-Ties; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it, appertains to make and use the same.

My invention relates to new and useful improvements in rail ties and resides in the provision of a preferably metallic rail tie which is formed in two parts and provided with spring means whereby a greater resiliency is provided than is the case with the ordinary wooden tie, and more durability and strength than is embodied in the ordinary wooden tie.

Another important object of my invention is to provide a rail tie of thecharacter described which will effectually prevent creeping and spreading of the rails which is often resultant in wrecks and. consequent loss of life, said functions being performed by a novel form'of rail securing means forming a part of my invention.

A still further object of my invention is to provide a tie which will remain firmly embedded in the road bed, consists of few parts and is cheap to manufacture.

The above and additional objects are ac complished by such means as are illustrated in the accompanying drawings. described in the following specification and then more particularlv pointed out in the claim which is a pended hereto and forms a part of this application.

With reference to the drawings. wherein I have illustrated the preferred embodiment of mv invention as it is reduced to practice, and throu hout the several views of which similar reference numerals designate corresponding parts. Figure 1 is a top plan view of mv rail tie showing the fas ening holding a rail upon one end thereof. Fig. 2 is a longitudinal fragmentary sectional view taken on line 22 of Fig. 1 showing the detail construction of the tie. Fig. 3 is a top plan view of the tie with the outer or top casing removed. Fig. 4 is a detail lan view of the rail clamping means. and Fig. 5 is a side elevation of a modified form of clamping means.

Referring to thedrawings the numerals Specification of Letters Patent.

Application filed February 13, 1914i SerialNo. 818,524.

1 and 2 designate rectangularmetallic 'casings each being open along one side and formed of some suitable metal. The casing 1 is disposed with its open side uppermost and 1s sl ghtly smaller than the casing 2 so that the casing '2 is placed over the casing 1 in slida'ble engagement therewith; The portions of each casing that? are adjacent the endsare enlarged and reinforced as at 3 for the purpose of giving strength to that portion of each casing wherein the weight of the rail and weight from the trains is placed. Adjacent each end of the casing 1 and centrally of the side edges thereof is formed an upstanding lug l having its upper end spaced from the outer edge of the side walls, of the casing. 'Mounted upon the lugs 4 are heli cal expansion springs?) having their terminals disposed in engagement with the casings 1 and 2. The lowermost edge ofthe casing 2 is normally spaced from the lowermost edge of the casing 1 and it will be readily seen that a great resiliency is provided the tie through'the medium of the springs 5.

As ameans for securing the rails A upon thetie I preferably provide rail clamping means designated 6 as an entirety. This rail clampmg'means cons1sts of coacting clamping plates 7 and 8 provided with rail base angular clamping flanges 9 and 10. Each, plate is provided with an outer edge opening longitudinalslot 11 arranged to receive a bolt 12 or othersuitable fastening means that is inserted through the upper face of the casing 2. The plate 7 is provided adjacent its inner edge withan offset portion 13 that is arrangedin spaced relation to the base of the casing-2 when in assembled'position and in bearing engagement with the rail base. This offset por-' tion 13 is preferably the same width as the' rail base and is'arranged to cooperate with I have illustrated a modified. form of rail clamping means. the numeral 15 designates an apnroximatelv rectangular plate that is provided with 'longitud nal end opening slots 16 to receive suitable fastening means after the same manner as in the preferred form. This plate 15 is provided intermediate and at a point approximately centrally of its ends with spaced angular and integrally formed rail base engaging flanges 17.

' It is to be understood that While I have 0 and that accidental derangement of the rails is prevented in that the shock in no Way'serves to loosen thebolts or cooperatingparts that are used for clamping the rails. The depressing of the outer casing 2 serves to keep the tie in the proper embedded; position upon the road bed.

In reduction to practice, I have found that the: form of: my invention, illustrated in the drawings and referred to in the above description, as the preferred embodiment, is the mosteflicient and practical; yet realizing that the conditions concurrent with the adoption of my device will necessarily vary, I desireto emphasize the fact that various minor changes in details of construction,

' proportion, and arrangement of parts may be resorted to,"'when required, Without sacrificing any of the advantages of iny invention, as defined in the appended claim.

What is claimed is A rail tie comprising, a pair of rectangular metallic telescoping casings, one Wall of each casing having thickened portions at its opposite ends extending into the terminals of the said ends, the said thickened portions on the Wall of one casing being opposed to the thickened portions on the all of the other casing, vertically disposed lugs carried by the thickened portions of one casing and arranged in spaced relation to the thickened portions of the other casing, springs surrounding the lugs and bearing against the opposed thickened portions of the casings, rail securing plates carried by the thickened port-ions of one of the casings, and fastening means extending through the plates and through the adjacent thickened b0 portions of the casing.

In testimony whereof I afiix my signature in presence of two Witnesses.
